Patent JP-S5968988-A (JP)
Title: Semiconductor laser
Inventor: UENO SHINSUKE
IPC: H01S5/10
Filed: 1982-10-12
Abstract: PURPOSE:To enable a large photo output oscillation and facilitate the manufacture by a method wherein shallow groove active regions at two parts are provided by isolation each other in the same plane in the londitudinal direction of a resonator, and a deep groove is provided in the neighborhood of reflection surfaces at both ends of the resonator. CONSTITUTION:The first shallow V-grooves 51 and 52 are formed in parallel at the center region of the resonator of a P type GaAs substrate 10, the second shallow V- groove 53 is formed on its extension, and a deep V-groove 54 is formed in continuity to this groove 53. At the region becoming the other reflection surface in opposition to the reflection surface wherein the groove 54 is formed, the deep rectangular groove 55 is formed in adjacency to the grooves 51 and 52. Next, clad layers are formed in the grooves 51-55, and then active layers, guide layers, clad layers, and cap layers are successively grown. This constitution makes it difficult to generate the chemical reaction with the outside because of no direct exposure of an excited region to the reflection surface and thus enables to block the deterioration due to the photochemical reaction of the reflection surface. Besides, since the neighborhood of the reflection surface is a layer of a band gap which is large to an oscillated light, light absorption is small, optical damages are difficult to generate, and accordingly the large photo output oscillation is enabled.

Title: Electron wave device
Inventor: TSUKADA NORIAKI
IPC: H01L29/06
Filed: 1989-07-11
Abstract: PURPOSE:To utilize the wave motion properties of electrons effectively, and to obtain an electron wave device having a switching funciton at ultra-high speed by forming constitution in which coupling strength among electrons propagating two electron channels can be controlled by gate voltage. CONSTITUTION:An Al gate electrode in an upper section is divided into three of A, B, C, and voltage can be applied to each of the gate electrodes independently. Electrons introduced from the input terminal F of a first channel are propagated in the primary electron channel of the first channel of the section A, and admitted into the section B. The first channel and a second channel are coupled in the section B, and the electrons of the first channel can be transferred to the second channel. Coupling strength between the channels and the length of the section B are selected properly, thus completely extracting electrons introduced to the first channel from the second channel in the same manner as the transfer of light in an optical directional coupler. That is, the input of the first channel can be extraced as the output of the second channel by applied voltage to the Al gate electrode of the section B or can be taken out as it is as the output of the first channel.

Abstract: PURPOSE:To precisely fit the run out of a cutting edge and improve the working precision by forming, on the lower surface of a tip body, a recessed groove part capable of being fitted to a protruding part formed on a tip mounting seat side. CONSTITUTION:A throwaway tip 15 is mounted on a tip mounting seat 14 by bringing its rear end surface 19C into contact with a mounting seat wall surface 14B, and fitting the lower surface 19B to the mounting seat bottom surface 14A side in the state where a recessed groove part 22 is fitted to a protruding part 17.

Title: Developing device
Inventor: OKAMURA TAKEHIKO
IPC: G03G15/09
Filed: 1989-07-12
Abstract: PURPOSE:To eliminate an irregularity of the density of an image and to obtain a stable development quantity by setting the rotary angular velocity and the number of magnetic poles of a magnet roller so that the radius and rotary angular velocity of a latent image carrier, the radius of a developer conveyance body, the rotary angular velocity, number of magnetic poles, and development nip width of the magnet roller satisfy a specific relational inequality. CONSTITUTION:The rotary angular velocity omegam and the number 2p of magnetic poles of the magnet roller 7 are so set that the inequality holds, where rd and omegad are the radius and rotary angular velocity of the latent image carrier 1, rs the radius of the developer conveyance body, omegam the rotary angular velocity of the magnet roller 7, 2p the number of magnetic poles of the roller 7, and (d) the development nip width. When omegam or 2p is made large, a magnetic force varies repeatedly at a short period in a development time when one point on the carrier 1 passes a nip part and the magnetic brush of a developer becomes rough and fine repeatedly. Therefore, a developing force distribution and a developer supply amount are similar at any development position and the stable development quantity is obtained.

Title: Solid-state image pickup element
Inventor: ISHIKURA HIDENOBU
IPC: H04N5/335
Filed: 1985-08-13
Abstract: PURPOSE:To prevent the production of residual signal charges and to improve the transfer efficiency, by providing a transfer gate having a width in the charge transfer direction smaller than or equal to the width of a vertical charge transfer channel. CONSTITUTION:A transfer gate 26 has a width WTG in the signal charge transfer direction smaller than the width WVCCD of a transfer channel 3. When the channel width is decreased, an impurity is diffused transversely from a channel- cutting impurity-diffused layer 32 and affects an impurity-diffused layer 33 which will be a buried channel. Therefore, the potential in the transfer channel connected to the transfer gate is also decreased. As a result, the transfer channel connected to the transfer gate is also affected by the impurity diffused layers on the both sides thereof and the effective width (WVCCD) of the charge transfer channel 3 is prevented from being extended. In this manner, the built-in potential well can be eliminated and the signal charge transfer efficiency can be improved.

Title: Manufacture of ultralow iron loss unidirectional silicon steel plate
Inventor: IGUCHI MASAO
IPC: H01F1/18
Filed: 1985-08-16
Abstract: PURPOSE:To provide an ultralow iron loss by forming an extremely thin tension film of TiC, TiN or Ti(C, N) on the surface of a steel plate by carbonizing and/or nitriding after forming a Ti-surface layer on a mirror-finished surface. CONSTITUTION:After an oxide on the finish-annealed plate of a directional silicon steel plate is removed, the surface is mirror-polished in average roughness of center line of 0.4mum or less by chemically or electrolytically polishing. After a thin Ti layer of preferably approx. 0.1-2.0mum thick is coated, for example, by depositing on the surface of the mirror-finished surface, the layer is carbonized and/or nitrided to form an extremely thin tension film of TiC, TiN or Ti(C, N) on the surface of the steel plate. Thus, magnetic property and specially iron loss property is largely improved together with the improvement of a film bondability irrespective of the presence or absence of the application of high temperature heat treatment such as strain removing annealing at high temperature in the use as a transformer material of a winding core.
